DONALD BARN MORISON, 01B HARTLEPOOL, ENGLANE specification of tetter's Patent.

Patented Dec.9,l9l3.

Application llled August 23, 1912. serial No. 716,648.

Th all whom it me concern:

lBe it known that T, DONALD BABNS Monrsoiv, a subject of the King of Great Britain and Treland, rcsidin at Hartlepool, in the ngland, haye invented Improvements in Steam-Regenerative Accurnul-ators and Water-Heaters, of which the following is a specification.

lln the wot-hing of steam regenerative acm cumulators and water heaters, such as teed water heaters,when a film or layer of oil floats on the surface of the water, the emciency of the-apparatus is decreased'and t is therefore very advantageous that the oil 5 should be removed.

The object of this invention is apparatus whereby the float oil is concentrated or collected in one or more desired parts of a steam regenerative accumulator or water 2 heater by surface li'ow, so that it can be readily removed.

In carrying out the invention according to one arrangement," the velocity oi the flow which results from the discharge of the it steam supplied to the accumulator or water heater through nozzles or the like, is utiliced for establishing a surtacefiow of water in a required direction toward and into a receiver in which the float oil is retained W and from which the outflow ot water is at 95 96?,142 of 1910, granted to me, there-is described a device in which a steam nozzle is placed within a water circulating tube, the water flow at the discharge from the tube being distributed radially. According to 49 the present invention, with such an arrangement, the discharge from each tube or its equivalent is so arranged that the flow is approximately in one direction, and when large numbers of these circulating tubes are employed the issuing streams are so arranged as to create a surface flow in one direction, the return flow, it may be, at a lower level being in the reverse direction. At the part where it is desired to concen- W trate the oil, as for example at one end 0t the vessel forming the accumulator or water heater, there is provided an oil collecting receiver which may be formed by an angle plate so arranged that the surface flow W passes through openings between the ends of the plate and the sides of the vessel into be a feed water heater,

a space between the plate and the end of the vessel, or there may be two directing plates and a central opening, or the surface How may be over a Weir tormedby an inclined plate. The plate or plates extend upwardly above the normal water level or into the steam space, and downwardly into the ,Water, the return flow of water-being between the bottom of the plate and the bottom of the vessel. The oil collecting receiver and the collecting pla' may betormed in any other convenient manner in order to facilitate the collection and retention of the oil, and may be placed in one or more parts of the vessel forming the. accumulator or water heater although it is preferable that the oil collector should be at one end so as to establish a regular surface ilow in one direction from one end of the accumulator or water heater to the other end, which besides concentrating the oil has a favorable effect in causing an increased circulation of water.

The invention may he carried out in various ways and may be applied in connection with liquid containing steam regenerative accumulators and Water heaters of any de sired type.

The accompanying diagrammatic illustratrons, Figures 1, 2 and 3; Figs. l, 5 and 6; Fig. 7 and Fig. 8 represent applications of the invention to a steam regenerative accumulator or feed water heater in.

which steam passes into a body of water, and Figs. 9, 10 and 11 represent convenient forms of steam condensing an'dwater circulating devices according to the present invention.

With reference to Figs. 1, 2 and 3, Fig. l 'is a vertical longitudinal section of a steam regenerative accumulator,

V Fig. 2 being a sectional plan view entire water line in Fig.

1, and Fig. 3 a vertical cross section on the" line A-A in Fig. 1 looking toward the left hand end of the apparatus. Steam enters the vessel a through the pipe 6 and passes through the distributing pipe 0 to the steam condensing and water circulat ing devices at which are so'constructed and arranged that the streams of water issuing from the outlets Z at the top of the circulating tubes (3 are approrrirnately in one direction as indicated in Fig. 2, so as to create a surface tlow toward the right hand end of the vessel where the oil and other floating or it may,

l kill matter carried by the surface flow of water is guided by the angle plate 6, and the steam discharge nozzles, through the openings f into the receiver 1" formed between the plate 6 and the end mof the vessel, the receiver 1" being fitted with a scumming device 9 by which the oil and other floating matter col- 5 a sectional plan view on the water line in Fig. 4, and Fig. 6 a vertical cross section on the line B-]3 looking toward the right hand end of the vessel. In this examplethe outlets Z from the circulating tubes (Z eX- tend above the water level and the receiver 9' is formed by the end m and the angle plate 0 which extends from side to side of the vessel and is provided with a central opening f through which the oil and other matter floating on the water iscarried by the surface flow into the receiver 1 from whence it may be removed by the scumming device p which is attached to the plug of the cock 0 so that by turning the handle t the pipe 11 may be placed at either side of the receiver.

Fig. 7 is a modification of the arrangement shown in Figs-4, 5 and 6, and in which, in order to trap the oil in the receiver and prevent a return flow through the opening f in the late 6, such opening is te'rminated slightly above the water level and is provided with an inclined plate 11. extending downwardly below the water level so that the surface flow of water is carried, by its velocity produced by the discharge of steam from the devices d, over the plate a and into the receiver 1".

Fig. 8 is a further modification of the arrangement illustrated in Figs. 4, 5 and 6, and in which the opening f in the plate '6 has a projecting lip s that forms with the flap w hinged to the plate 6, a non-return valve, the return flow of oil and other floating matter being prevented by the automatic closing of the valve when the surface flow of water through the opening f ceases.

Figs. '9 and 10 illustrate a convenient form of steam condensing and water circulating device for the purpose of causing a uniform flow of water in a desired direction. Fig. 9 is a sectional elevation on the line CC of Fig, 10, and Fig. 10 is a sectional glam view on the line DD in Fig. 9.

team is supplied to the nozzle 2 through the pipe 1 and is discharged upwardly into the surrounding water through the outlets 3, whereby the steam is partly orwholly condensed and an active upward circulation of water produced in the tube 1. The outlets 5 at the top of the tube are formed at one side thereof so that the upwardly circulating water is discharged from the tube in approximately the same direction, for the purpose hereinbefore set forth. In order to further promote the surface flow of water, openings 6 may be provided for the discharge of steam from the central pipe 1 through the water outlets 5, and although the openings 6 are shown below the water level in the arrangement illustrated, they may if so desired, be situated above the water level and discharge a jet of steam on to the surface of the water for the purpose of forcing the oil and other floating matter in the direction desired.

The steam condensing and water circulating device illustrated in Figs. 9 and 10 may, instead of having two outlets for the circulated. water, have one only, as shown in sectional plan view in Fig. 11.

Although, by way of example, the steam discharge nozzles described inthe specification of my Letters Patent No. 967,142 of 1910 are referred to as a means for creating a surface flow with the object set forth, it' is to be understood that the nozzles may be otherwise suitably constructed and that any other suitable means may be employed for creating a surface flow.

What I claim is 2- 1. A steam regenerative accumulator having submerged steam condensing and water circulating devices, consisting of circulating tubes, steam discharge outlets disposed within said circulating tubes for directing a surface flow of water toward one end of the accumulator, water outlets in said circulating tubes arranged at one side thereof adapted to cooperate with said discharge outlets for establishing a surface flow in one direction, substantially as described.
